The Bull Rush is the first thing that comes to mind when you ask this question. (I think Brian Ballsun-Stanton's comment is foreshadowing this), which requires a charge attack.

BULL RUSH: STANDARD ACTION(PHB1, p287)

Target: You can bull rush a target adjacent to you that is smaller than you, the same size category as you, or one category larger than
you.

Strength Attack: Make a Strength attack vs. Fortitude defense. Do not add any modifiers for the weapon you use. Hit: Push the target 1
square, and shift into the vacated space.

Impossible Push: If there’s no square you can push the target into, your bull rush has no effect.

MOVE A GRABBED TARGET: STANDARD ACTION(PHB1, p290)

Strength Attack: Make a Strength attack vs. Fortitude. Do not add any weapon modifiers. Hit: Move up to half your speed and pull the grabbed target with you.

Beyond those, I can't find any untrained ways to move someone (IE powers, feats, etc.) short of Bankuei's reference to DMG1, p42 for improvised actions, the example of which includes a push type action.

+1 Bull Rush and Move a Grabbed Target are the only untrained ways I'm aware of too!

Bull Rush doesn't require a charge attack as far as I'm aware (although that's the most common use of it that I've seen). DDI's glossary entry for Bull Rush mentions no such requirement, either.

D&D4E's pg. 42 of the DMG has guidelines for stunts. The general gist is that as players come up with random stunts, the GM can assign a stat to attack with, a defense stat for it to go against, an amount of damage, and conditions.

"I roll a barrel down the stairs at the goblins" - could/should easily result in forced movement (down the stairs).

Of course, this depends on what objects/terrain is available, the monster(s) you're fighting, and the GM's ruling about each particular stunt you're doing.
